Science shorts, I am forever in your doubt .... the Cyclotron you explained in full details with the derivation of it , and the magnet on the balance and finding magnetic flux density and many more ... the exact same scenario Came to the AQA exam paper 2 ... I couldn't do them if it wasn't because of your help. I really hope something really good happen in your life because you have just made my hope of getting an A grade in ALEVEL physics to come alive again . Thanks a lot
I'm usually not the best at concentrating (adhd things), but your videos got me hooked up! I've been watching non-stop for 3 hours, so easy and clear, thank you for your work!
Science Shorts 😂😂😂 I don’t think you need ads, the video quality field strength is strong enough to attract the students. (Can’t believe you actually replied 😭)
For the flemings left hand rule, u can use the following to remember what the fingers indicate: Father: Force(thumb) Mother: Magnetic field direction(index) Child: Current(2nd finger)
Hi, my teacher recently showed a nicer way to remember flemming left hand rule being that, your hand looks like a gun so you must be the FBI. Then just remember it in that order being F(Thumb) B(Index Finger) and I (middle finger). just a little easier way to remember. Great videos man keep them up, hopefully i can bag an A in physics because of you. Thanks man
This is awesome, I love your videos. Do you think you could do a video with key word definitions for every topic? I feel like it'll help a lot of people cause key words are a pain and difficult to remember.
A tip to rember the 11:06 section Which hand to use and for what MotoR has one R so it's the LHR (left hand Rule) GeneRatoR has two Rs so it's the RHR (Right hand Rule)
an easy wat to remember what the fingers stand for with Flemings left hand rule is using F=BIL. starting with the thumb, which represents force, they are in the same order as the equation.
Quick way to remember what hand rule to use. Right hand rule is generating so its basically gene-right-ing. IM very late to this video but wow is it helpful - A-levels in 2 weeks and looking over last years papers i need to do a lot more work.
Another way to remember the Left Hand Rule is by remembering it as (Thumb) Father - Force (Index finger) Mother - Magnetic Field (Middle finger) Child - Current
The video was great!! In detail as well ... I had a doubt: In the example, we need to think in a way that the wire will experience an upward force and instead the magnets will be pushed down as the wire is fixed. Why do we not consider the force to be moving downwards itself ? Thank you.
S-sir, this is a brilliant and concise video and I truly appreciate it... ...However, that six-fingered "hand" at 9:36 IS GIVING ME A LAUGHING SEIZURE 💀💀💀
for flemings rule my teacher told us to use "father, mother child". from the thumb to middle finger. father being force, mother being magnetic field, and child being current
thank you so much for your work! A-Level Physics is super hard for me and my teacher's really difficult to deal with. Your videos help a lot Much appreciated :>
A good way to remember Earth's magnetism: A compass that points North is pointing to the North Geographic Pole but since North is attracted to South, the North Pointer is actually pointing to the Magnetic South Pole
Finally someone who can teach. I've watched an unbelievable number of videos on this subject. I knew it was basic simple but our education system produces simpletons instead of teachers. Thank you thank you thank you.
Hi Science shorts great vid as always, my question is at 16:45. why is the force acting on the wire upwards if you want a downwards force on the scale to get a reading? thanks :)
For anyone who cant remember which finger represents what for the left hand rule, use Father, Mother Child, so first finger force second finger magnetic field B and last is current I
Thank you a lot.🧘♂️ I have not done any research, I just guess it’s right what you explain 😂. Tell me pls, How can I imagine this situation: I hold 2 magnets in each hand. Pushing n side to n side. (Magnetlines never cross nor break) but how do the M-lines look like (ofc quality not exactly) if I manage to push the magnets together so they touch each other complete. Like this: "ll" but without space in between 🙈😄don’t know how to say properly.. are the m lines in line, straight and complete? And the stronger the Magnet is the more lines it has too? Are these lines stackable?^^ I hope you understand what I try to say and what I thought of^^ best regards
I can only answer one of your questions with confidence: yes the stronger the magnetic force in the field, the more lines it has or at least the closer the lines.
can we explain why does the geo. North of earth is also its South magnetic pole and vice versa. Like if the magnet points towards the north then why is it the south of the earth?? Is it like the examples you made like the one with two aligned magnets? Thankyou to anyone who helps me understand this
Thank you for the nice explanation! But I think I prefer to think right hand rule for the direction of the force. We can keep our thumb as the direction of the current (as in the original right hand rule), then point with index finger towards the direction of the magnetic field, which leads your palm to face the direction of the force :D
I spent all my time revising the first year stuff, so I have been really panicking about the second year stuff. I still don't expect that good a mark, but these videos are fantastic, and have given me a chance lol. Thanks so much 👍
Ampère, was inspired by Hans Christian Ørsted, and came up with right-hand screw rule, coffee-mug rule or the corkscrew-rule. Orsted discovered deflecting compass in 1820, electromagnet discovered in 1825 by Sturgen, 1831 first dynamo by Faraday, 1832 DC motor by Sturgen, In 1823 Ampère's originally derived the rule, this was when he was studying effects of current directions between two conductors.
Quadrupole magnets, abbreviated as Q-magnets, consist of groups of four magnets laid out so that in the planar multipole expansion of the field, the dipole terms cancel and where the lowest significant terms in the field equations are quadrupole. Quadrupole magnets are useful as they create a magnetic field whose magnitude grows rapidly with the radial distance from its longitudinal axis. This is used in particle beam focusing.
From GCSE, I remember the Left/Right hand rule fingers with "My Furry Cat". *Thumb:* My - Motion *First finger:* Furry - Field (magnetic) *Second finger:* Cat - Current
Hi, on the equation B=mg/IL You wrote out the following 0.05×9.8 / 1x0.1 I'm confused as to where the 9.8 came from as I haven't seen an explanation or may have missed it. Can you please explain, or perhaps someone from this community. Thankyou, B
if you have a mass then the force would be its' weight. F= ma and the acceleration caused by gravity is 9.81 which is where the 9.8 comes from so on earth F = 9.81 x mass
A quick way to remember Flemings left hand rule is using FBI, Force for thumb B for first finger (field lines direction) and I for current direction, but it comes at a cost because everytime you use this you have to shout FBI OPEN UP, use with caution
I am utterly confused. MIT teacher uses his right hand to show field, direction, and force, but you're using your left hand. it's conflicting. so which is it? I would assume the MIT teacher is right on using your right hand. I am not talking about the field using the right-hand rule either. I am referring to the appropriate hand to figure out force induced by current and magnetic fields.
Why is it that the magnetic flux density is so high (in the example @ 18:21) when the numbers you plugged in seemed so benign? Can I create this flux density at home?
I really want to express my heartfelt thanks to you as you've taught me what my teacher was trying to teach for 2 weeks, in just 20 minutes.
How did a level go? 🤣
For anyone who cant remember which finger represents what for the left hand rule, use FBI so first finger force second finger magnetic field B and last is current I
We got taught that too, our teacher just kept shouting "FREEZE, FBI" whilst doing the left hand rule as if it was a gun
can i safely assume that magnetic flux density is the same as magnetic field strength?
i learnt it via FMC - first finger F stands for Father, second finger M stands for Mother, third finger C stands for Child
Father Mother Child
if you can't remember the left or right hand, there's really no point in trying to memorize ....
@@encheng2664 Nice!
8:01- RH rule

you only use 5 fingers ,jezz infact there are only 3

For the flemings left hand rule, u can use the following to remember what the fingers indicate:
Father: Force(thumb)
Mother: Magnetic field direction(index)

Or
FBI
F=force
B= b field

What grade did you get in a level physics in the end?
Imagine being in a gcse exam and pull out a left hand rule. Inspectors around you will think that youre pulling up some gang signs.
Why do you want the force to go upwards (away from the scale) and not just directly down into the scale?
This is awesome, I love your videos.
Do you think you could do a video with key word definitions for every topic? I feel like it'll help a lot of people cause key words are a pain and difficult to remember.
@scienceshorts yes please
Would totally love to see one on Electromagnetic Induction, AC Generators and Transformers! This video was super helpful! Thanks :)

Shout out to his Fleming Left Hand 👏🏻
A tip to rember the 11:06 section
Which hand to use and for what
MotoR has one R so it's the LHR (left hand Rule)

Hello, at 17:07 do the forces follow Newton’s third law. As you stated equal?
Well I'm glad that I found this the night before my exam!
The video was great!! In detail as well ...
I had a doubt:
In the example, we need to think in a way that the wire will experience an upward force and instead the magnets will be pushed down as the wire is fixed. Why do we not consider the force to be moving downwards itself ?
Thank you.
In the experiment part
Why does the magnet move downward
THIS WAS SOOO HELPFUL! 100% going to share with friends, extremely helpful and simple information. Thank you!

this is called the perfect lecture, made us study with 100% concentration, but even made us laugh during left hand rule:))))))
thank you for your videos, currently teaching myself what i missed in class due to illness
I've watched multiple other videos, but this one actually explained what is going on in detail
for flemings rule my teacher told us to use "father, mother child". from the thumb to middle finger. father being force, mother being magnetic field, and child being current
wow good

Is there a finite amount of field lines around a magnet?

Newton's 3rd law I think
Anyone here in quarantine
Yes me
Shortcut to remember left hand and right hand rule
Thumb-index-middle fingers are Force(F), magnetic field (B) and current(I)
Which is simply FBI
Many many Thank you sir..
I have caught all the concept from this video..
Take love❤️🇧🇩
Easier way to remember left hand rule is (from thumb first finger then second) FBI -> force (F), Flux density (B) , Current (i)
You're so underrated.
For anyone who cant remember which finger represents what for the left hand rule, use Father, Mother Child, so first finger force second finger magnetic field B and last is current I
My teacher just said its "Force Field", " - current". For the LHR.

AN S thanks 4 the answer 👍🏻 You def. helped me by that
Was Maxwell able to state his "right hand rule" simply mathematically without reference to the human hand?
can we explain why does the geo. North of earth is also its South magnetic pole and vice versa.
Like if the magnet points towards the north then why is it the south of the earth??
Is it like the examples you made like the one with two aligned magnets?
Thankyou to anyone who helps me understand this
UHAAAA THANKS SO MUCH SIR !
heres my thanks! muah~
Nigga help
This was super helpful but I just couldn’t stop laughing when I looked at the hand you drew for Flemings left hand rule
WHY DOES EVERYONE HATE MY HAAAAND :'(
16:38 wait why do we want the force to go up?
Why does it being the magnetic north and magnetic south pose a problem?
Great video but This video didn't cover angular speed and theta.
This is in gcse triple now
I remember left hand rule as FBI - from thumb to middle finger force b field current
15:04 Excuse me, Is this a series circuit in this experiment?

Thank u soooo much!! Please can u do a video on vector diagrams and calculating magnitude/direction for GCSE
such a helpful guide which actually related to OCR SPEC A (new spec)
very educative. Thank you Regards
The hand had 6 fingers... I'm sorry but it was actually disturbing!
That very fingerist of you.
Trust me. I draw the exact same fleming "left hand" as u
Can anyone tell me what flux linkage is? Thanks
Have my physics mid in 20 mins thanks for this 😂
I'll be writing this in 8 hrs time, I'm now in a better position so thank you.
Thank you for the nice explanation! But I think I prefer to think right hand rule for the direction of the force. We can keep our thumb as the direction of the current (as in the original right hand rule), then point with index finger towards the direction of the magnetic field, which leads your palm to face the direction of the force :D

what exists between the lines of magnetic fields?
That was so great. Thumbs up !!

feel so sorry for aliens tryna do these hand rules

Thanks for the informative video - I was wondering if you've made any videos which refer to hall probes (part of magnetic fields/flux)
Thanks for this, my notes aren't great
I'm not even A level just puzzled by magnets u really helped simplify
I have no teacher due to lock down you are my hope
Have you done angle of dip and declination

The most powerful part of a magnet is the "B" field, that is the center of a magnet, N- S would not exist without the "B" field
10:00 that hand has 6 fingers lol
Thank u very much sir🫶
Thank u very much sir🫶
☺love that 3D hand drawing, very insightful lecture🔥👍
Why is it that the magnetic flux density is so high (in the example @ 18:21) when the numbers you plugged in seemed so benign? Can I create this flux density at home?
Please make more videos about particles physics such as particle interactions
if the coil of wire had a 100 turns would ur force increase by that n amount but magnet field stay the same since = F = nBilsin
Whyy there is a force on pan balance instead the wire is move upward?explanation .. Due to newton 3rd law??
Yep!
May the Aleph (god of wisdom and life) bless you.
